Sessions & Messages

Manage DSH sessions the way Windows Explorer manages files: move, delete, search, archive, favorite and flag sessions as to-dos, and organize them with tags, notes and folders across workspaces. An AI pass can summarize a session and write its notes and tags in one go.

Visual branch brainstorming that creates an isolated Session for each direction, automates parent, sibling, checkpoint, and return Handoffs, and provides a full tree tab with an optional Better Sidebar view.

Imports sessions from pi, opencode, codex, claude-code and WorkBuddy into DSH, unifies AGENTS.md, skills, project and per-agent memory across harnesses with symlinks instead of copies, and migrates Codex and WorkBuddy automations into DSH scheduled tasks.

Auto-compaction that writes a handoff note first: as a session approaches a token threshold it asks the model to save a project checkpoint into the workspace, then optionally starts a fresh session seeded with a continue instruction and parks the old one. The note must be written within the current compaction cycle and its conclusions section must actually change, so a stale or merely touched file cannot slip through.

Two-way sync of DSH sessions, workspace mappings, settings and patches between machines through your own private GitHub repo (API keys stay machine-local).

Injects one system-prompt section so the agent's chain-of-thought, planning and tool-invocation reasoning stay in Simplified Chinese. Zero external dependencies - clone and link-install from any local directory, no npm build or publish required.

Visual conversation map for DeepSeek Harness — sessions as cards on a whiteboard: drag to arrange, double-click to chat, draw an edge to fork with injected context. ADHD-friendly spatial memory. · DSH 可视化对话地图

Injects a per-session x-opencode-session header into opencode.ai inference requests, fixing the OpenCode Go gateway 400 MissingSessionID error; server-only, no UI (npm: `dsh-my-opencode-session-header`).

Zero-residence context engine: large tool payloads are evicted out of the live context into a queryable store and only deterministic pointers are left behind, so per-turn prompt tokens stop growing with the transcript. Any masked content is reconstructed verbatim from the session log on demand, by tool-call id or session seq.

Finder-style session labels: a hover button next to archive and pin, plus the native context menu, assign coloured labels; titles can take the first label's colour or a label symbol; view options gain a filter by label applied before grouping. Labels are stored by the Host and shared across workspaces. Needs DSH 0.2.2-rc.1 or newer and Node.js 24.9+ (node:sqlite); the interface is available in Chinese and English only.

Same-origin in mechanism with the two loudest lines in context compression. The code-skeleton gate follows the skeletonization approach of Headroom (Apache-2.0), whose published headline is 20% fewer tokens for coding agents and 60–95% fewer tokens for JSON, same answers. The estimator channel follows TokenPilot (arXiv:2606.17016), which reports up to 60% lower cost for long-session agents. Both figures are theirs, quoted as-is; this plugin ships no benchmark of its own and claims no reduction of its own. What it adds for DeepSeek Harness: choose a compression profile, set the Auto Compact trigger level and toggle code-skeleton compression from one settings section, with exact DeepSeek V4 tokenizer measurement, same-revision count verification, and fail-open behaviour that keeps the original tool results on unsupported models. Within a turn it supports skeletonized information compression with a low original-text retrieval rate; at the tail of a turn it supports a turn-tail intent summary implemented purely by content substitution; context content stays safe, and the whole process runs inside the official JSONL compression.

Recycle bin for DSH sessions: sidebar delete icons, multi-select restore and permanent delete, live-session protection.

Idle session reminder: prompts to archive sessions untouched for N hours, with a snooze window after each refusal, using the official archiveSession API.

Replay sessions on a playable timeline with per-step token usage, audit sensitive operations, estimate cost, view fork lineage, compare sessions, and export standalone HTML replays.

Archive, unarchive, and delete sessions from a settings page.

Move sessions across workspaces by drag-and-drop with true in-place migration; recover orphaned or unregistered sessions; re-point stale workspaces after folder renames. IDs and history stay intact, with per-step backup and rollback.

Draws every branch of a conversation as a clickable tree beside the chat, with favorites, custom icons and colors, branch merge and split, rewind-aware layout, and Claude Code branches that keep their memory.

Sidebar session search that builds its own index instead of reusing DSH's full-text one: title to content toggle in one entry, results grouped per session with the strongest snippet and user/reply/tool tags, plus watermark-based incremental sync, archive-driven pruning of archived sessions, and a shadow rebuild that never blocks the live index.

Peak-hour auto session gate: weekend mode + global peak auto-pause + session-level freeze/resume + backend auto-retry, auto-resume on off-peak.

Repair DeepSeek Harness sessions that refuse to load, with a sidebar Session surgeon overlay and dry-run repair.

Guarded context compaction for DeepSeek Harness (dsh): the LLM proposes, deterministic guards dispose — eager per-atom shrink (extract/summary/false under verbatim guards) + lazy reference-graph eviction (0-LLM) + byte-exact recall from an append-only log.

`/side` persistent side sessions and `/btw` one-shot side questions, run in a temporary fork without touching main history.

Browse every message you sent in the current session: full-history listing with newest-first sort, text filter, one-click copy, and jump to a message (auto-loads earlier history when the target is not yet loaded).
